The active component of Kamagra oral jelly is sildenafil citrate, which is one of the most well-known medications for ED. By improving blood flow to the penis, Kamagra helps men get and keep an erection strong enough for engaging in sexual activity. Take Kamagra Oral Jelly approximately half an hour before engaging in sexual activity. Because the jelly is liquid, it may take effect more quickly when spooned onto the tongue and consumed. It is recommended to use one sachet at a time. After opening the sachet, you can either spoon-feed the jelly into your mouth or just pop it into your mouth. It is not appropriate to eat or smash it. The medication will work best if it is swallowed whole, without the use of water.
